House Limits Trump's Iran War Authority; GOP Defections Fall Short of Veto-Proof Margin

The House voted 214-208 on July 23, 2026, to curb President Trump's power to wage war against Iran, with four Republicans joining all Democrats. It is the first such vote since a US-Iran ceasefire collapsed in early July, sparking twelve days of fighting. The margin falls short of the two-thirds needed to override a presidential veto.
